Title: Carrier device used in special environment
Inventor: SUZUKI NOBUYUKI
IPC: B65G49/00
Filed: 1990-07-31
Abstract: PURPOSE:To lighten a movable piece such as a slider and enhance positioning accuracy by separating an outside special environment from an inside atmosphere with a pipe of non-magnetic substance, and magnetically coupling a driving means that moves in the pipe and the movable member in the special environment. CONSTITUTION:A group of electromagnets 9 are respectively provided at the front half part and the rear half part of a moving member 6 to levitate a slider 1 by electromagnetic attraction force, and make it capable of magnetically coupling. A driving part that moves the slider 1 is packed in a non-magnetic metallic pipe 2. A timing belt 12 is moved by a timing belt driving motor 14 through a pulley 13a, and the movable member 6 is moved in the pipe 2 to the direction of an arrow A. On the other hand, since the slider 1 is levitated by electromagnetic attraction force due to the magnetic action between soft iron 5 mounted and the electromagnets 9 mounted on the moving member 6, and combines with the movable member 6, the slider 1 travels along the pipe 2 in response to the movement of the movable member 6.

Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To enhance visibility by removing unnecessarily shining rays of light, in the case of a structure using a light emitting diode for lighting a transparent substrate superposed on a liquid crystal panel. SOLUTION: In this surface-like lighting system, a bar-shaped light guide body 3 provided partly with prism-shaped portions 3a as optical-path converting means is disposed on one end of a transparent substrate 2 and the light from a light emitting diode 4 comes into the transparent substrate 2 via the light guide body 3.
